Electromagnetic emissions refer to the waves of energy that are produced by various sources, including natural phenomena and human-made devices. These emissions encompass a wide range of frequencies, from low-frequency radio waves to high-frequency gamma rays. Common sources include cell phones, radio towers, and the sun. These emissions can travel through space and can interact with matter, leading to various effects. For example, microwaves are used in cooking, while X-rays are utilized in medical imaging. Understanding electromagnetic emissions is essential for assessing their impact on health and the environment.
